Today we continued the chapter on mutation, discussing how to find the origin of a mutation in a sex-linked gene. We also talked about how calculate mutation rates in humans, when they are visible in the phenotype. We defined the conditions under which such calculation is possible.
We mentioned factors that determine variation in mutation rate in different genes and factors that increase such rate. We introduced the concept of radiation as a mutagen and started describing the most common sources of it and mechanisms of action.
